Spectrum DSP M2 User Manual

Spectrum DSP M2 User Manual V1.1
Configuration Menu:
The second item of the main menu item is “Configuration Menu”. Open the “Configuration”
Menu” using the stylus to access the settings.
General radio setup related items:
• Rig Model – Select the transceiver or receiver to be used with the Spectrum.
• CAT Protocol – This is set to the default value for the selecte rig.
• CAT baudrate – Again set to the default vaue for the rig.
• CAT mode – The Spectrum can operate as a Slave, Master or in BiSync mode, where
both the transceiver and the Spectrum can control operational frequency and mode.
• IQ Mode – The IQ signals can be swapped in software to meet the connection
requirements of varios radios. If the IQ signals are reveresed, USB will operate as
LSB and visa-versa, and the peaks on the Scope will run in the wrong direction while
tuning.
• CAT TX PTT – If enabled, PTT commands will be processed via that CAT serial
connection, and the EXT DIT/DAH lines will be ignored.
• Band definition – The various band definitions for each region can be set.
• Save out-of-band freq. - This allows the last frequency to be save during power-down
even if it is outside a legal band.
• TX on out-of-band freq. - This allows TX activation outside of the legal bands.
• Transmit disable – Disable the TX function.
• Step Size Marker - When set to ON a line below the appropriate digit of the main
frequency display indicates the selected step size.
• Transmit Disable - When ON, all transmit functions are disabled. This may also be
toggled by pressing-and-holding the TUNE button. An indication of Transmit Disable
being active is the TUNE button's text being displayed in grey.
• O/S Menu SW on TX - (“On-Screen Menu Switch on Transmit”) When ON several of
the receive-specific adjustments (“AFG” and “RIT”) are switched to transmit-specific
adjustments, such as “CMP” and “MIC” or “LIN” in voice modes, respectively. This
allows more convenient access to these parameters when in transmit mode. CW-
related functions are not available in this manner.
• Mute Line Out TX – This enables/disables the muting of the LINE OUT mode when in
TX mode. The LINE OUT is always disabled when “Frequency Translate” mode
is active.
• TX Mute Delay – This causes the transmit audio to be muted for a brief period after
activating the PTT line with the settings depicted in 100ths of seconds. The range is
from 0 (disabled) to 25 (250 milliseconds.) This may be used to suppress a “click” or
“clunk” produced by microphones when the transmitter is keyed, particularly electret
types that are powered up at the moment that the radio is keyed.
• LCD Auto Blank – With settings of “Off” and adjustable from 5-15 seconds, this
enables a feature in which the LCD backlight will automatically blank after the
configured number of seconds after a button was pressed or knob turned when NOT in
MENU mode. This mode may be used to reduce power consumption – particularly
when the transceiver is being battery-powered. When the LCD backlight is turned off,
the spectrum scope and waterfall are are also disabled (“frozen”, actually), reducing a
potential noise source as well.
• Filter BW Display – This setting sets the colour of a line below the Spectrum Scope or
P 39
